        SCSI drives can be moved either direction, it's just that
SCSI drives provided by Apple were 'blessed' by Apple with a ROM that
provided additional information to the HD setup utility provided with
the OS. Vendors of 3rd party drives that didn't have this ROM had to
provide thier own formatting software specific to the drive or a
generic formatting software such as FWB HD Toolbox (this was even
provided as standard with a number of the Mac-clones, including those
from Power Computing). The Apple ROM drives were still usable on
non-Mac systems just fine. Thankfully, this type of thing is no
longer done with the IDE drives used on the newer Mac's.
